IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 126,674, dated May 14,1872.

Specification describing a new and useful Improvement in VVater-Wheels,invented by TENISON CHEsHER, of West Middleburg, in

r the county of Logan and State of Ohio.

This invention relates to a new and useful improvement in water-wheels;and consists in the construction and arrangement of parts hereinafterdescribed.

In the accompanying drawing, Figure 1 is a sectional side elevation of amovable chutecylinder, showing the manner in which it is operated. Fig.2 is a horizontal section looking down from the line so a; of Fig. 1.

Similar letters of reference indicate correspondin g parts.

A is a stationary curb, which surrounds the wheel and chutes, made inone or more sections, having a partition-plate, B, with orifices Otherein, through which orifices the water is discharged onto the bucketsof the wheel. On the inner side, above the partition-plate of the curb,is a stationary chute, I, for" each of the openings 0. These chutes areplaced at the proper angle, and bolted to the curb. E is an interiormovable cylinder, of smaller diameter than the curb A, provided with abottom, F, and an outer flange, G, the latter of which extends to thecurb, with openings 0 therein to correspond in size and position withthe openings (J in the partition-plate B. H represents a series ofchutes, which are attached to the movable cylinder E. In width thechutes H and I are equal to the distance between this cylinder E and thecurb, so as to fill the annular water-space J between the vertical partsIt will be observed in Fig. 1 that the chutes stand at different angles.The bottom and the outer flange of the interior cylinder E rest upon thepartition-plate B. K is a boss or hub raised on the partitionplate B,and forming a guide, around which the interior cylinder E is turned orgiven a revolving motion sufficient to open and close the water-apertureO in the plate 13. This revolving or circular motion is produced bymeans of the rods L L, connected with the cylinder, as seen at m m, andwith the arms n n of the vertical shaft 0. Motion is imparted by meansof the lever P attached to the top of the shaft. Q is the water-wheelbed-timber, and His the framework for supporting the shaft 0 and thewaterwheel shaft. 1

It will be seen by this arrangement that half the chutes are stationaryand half movable,

and that when the movable chutes are drawn back from the stationarychutes the wedgeshaped opening between them is preserved at all times,whether the opening be more or less. The current of water is not brokenbefore it strikes the bucket of the wheel, and the full force due from asmall quantity of water as well as from a large quantity is secured.

In this example of my invention I show the chutes adapted for ahorizontal wheel, but the same arrangement of chutes may be applied towheels with horizontal shafts.

Havingthus described my invention, I claim as new and desire to secureby Letters Patent- 1. The curb A, with openings 0, stationary chutes I,partition-plate J ,"raised hub K, and interior movable cylinder E, withflanges F and G, openings 0, and chutes H, when the same are arranged tooperate substantially as and for the purposes described.

2'. The combination and arrangement of the stationary and movable chutesI and H, as and for the purposes described.
